When I started working where I am now I made friends with this girl and we started becoming really good friends! we lived together for a few months and during those few months I made friends with two of her other friends who are boyfriend and girlfriend! We stopped living together because of money problems she had.I broke up with my boyfriend and was having a really hard time of it and her two friends I made friends with were always there for me more than her, she was always picking her boyfriend over all of us! So me and these two friends and another fella became very close. We do stuff together every weekend the 4 of us, we always asked her with us at the start but always refused because she would be with her boyfriend so eventually we gave up asking her! Then the ing started! She started telling the other girl in our group that she hated me and not 2 trust me that I fancied her boyfriend and never to invite her anywhere I was going because she didn't want to be around me! Then she would to me about the rest of them to me that she hated them and that dey never made time for her any more! We confronted her the other day by text and she denyed everything! I suggested we should all meet and sort this out together! At first she wanted to sort things out with me first alone and then with the rest but I refused and said we will all sort this out together and then she turned on me and sent me this text message "no its like this i am friends with them way longer than you. i dont trust you what so ever why would i want to sort anything out with you? i know u fancy **** thats why i gave ***** the heads up because you can't b trusted and thats that sweetheart! your a snake every 1 in work says it" I've never done a thing to her or anybody in work to be called that!and am pretty upset over it what should I do?

She is probably feeling that since you were in the picture, you 'stole' her two best friends, and if you managed to steal them, you are probably after her boyfriend too. That would leave her all alone without anybody.

She is likely insecure about your motives and intentions, because you are the new one to an otherwise established group of friends. I'm not saying you have caused trouble, I'm saying that trouble started with the group, after you were solid friends with them too. At least for her.

I would not confront anybody with an IM, that is cowardly.

If you have nothing to hide, and you are sincere in talking this out with her, then set something up, with just you and her. Don't involve the others because that would feel to her like you are all ganging up on her.

After you have had a good talk, and sort things through- hopefully. Then, maintain the peace and confidence you have established with her, and if the others are concerned about their relationship with her, they can do what you have done, and talk to her directly.

Hopefully with peace being made with you taking the lead, everybody will get back to normal, and feelings won't be so hurt.

OK wel just say I hang around with paul sarah and sean!and the girl we have fallen out with is libby! Paul and sarah are boyfriend and girlfriend but libby is telling sarah that I can't be trusted and that I fancy paul which I definitely don't!trying to cause trouble between me and sarah!
And telling her she hates me!but then she was turning around to me and ing about sarah and paul that sarah isn't around any more that she's always with paul!
You see libby was always friends with sarah, she was never friends with paul or sean(paul and sean don't really have anything to do with the arguing). I didn't make with friends with an already formed group of people we ended up just hanging together one day and every weekend since then we have been together! We definitely didn't cut her out we always asked her with us and always turned us down for her own boyfriend! we just felt then that she was picking him before us!
Should I still talk to her on just her own or should the three of us girls sort it out together? Or is there even a point in talking to her if she hates me and thinks I can't be trusted?

If it were me, I would probably still talk to her about her relationship with you, not everIybody. You can really only speak for yourself, and speak to what you have heard that she has said. Sometimes just confronting things will put a stop to it.

If you think that she will be okay with a sort of 'showdown' with all of you girls talking, try.

Either way, if it were me being accused of underhanded things like trying to steal a boyfriend from somebody else that I have no interest in, I'd most certainly set that rumour to rest with her.
